Large Particle, High Mineral Purity Delaminated Kaolins and Methods of Preparing and Using Same

摘要

Disclosed herein are compositions comprising novel delaminated kaolins having a large particle size and low levels of alkali metal oxides. Methods of making the disclosed delaminated kaolin by calcining hydrous kaolin are described. Applications using the disclosed compositions in preparing catalyst substrates, paints, coatings, sealants, cementitious products, ceramics, rubbers, polymers and other compositions are also described.
